Join Alyson Hannigan in Her March of Dimes Pledge! (VIDEO)

Being a mother is the hardest job in the world, but it’s also the most rewarding — just ask Alyson Hannigan!

The 37-year-old actress is mom to 2-year-old Satyana, and has been learning all kinds of new things all along the way. Since she’s new to the motherhood, she wants to help out as much as she can!

So, how can YOU help?

All you have to do is head over to Johnson’s Baby Facebook page and Like them! For every like they receive, they’ll donate $1 to the March of Dimes which helps families treasure the joy of a healthy baby.
